應用

Urea is typically used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. It is useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. Urea may be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.

用于蛋白质变性以及作为不溶性或变性蛋白的温和增溶剂。可用于从已由 6M 盐酸胍变性的样品(如包涵体)复性蛋白质。可与盐酸胍和二硫苏糖醇 (DTT) 一起用于复性变性蛋白以恢复其天然或活性形式。
